The operation and, particularly, the decommissioning of NPPs and radiochemical plants result in substantial arisings of radioactive metal waste (RAMW) having different activity levels (from 5×10 -4 to ≈ 40 Ci/kg).This paper reviews the specific features of the technology and equipment used to melt RAMW in electric arc and induction furnaces with ceramic or "cold" crucibles. The experimentally determined and calculated data are given on the level to which RAMW is decontaminated from the main radionuclides as well as on the distribution of the latter in the products of melting (ingot, slag, gaseous phase).Special attention is focused on the process and the facility for the induction-slag melting of RAMW in furnaces equipped with "cold" crucibles.The work described is under way at SSC RF VNIINM to master the technology of melting simulated high activity level Zr-alloy and stainless steel waste.

Представлены результаты биохимического и морфологического анализа крови чистопородных и помесных баранчиков, рожденных в разные сезоны года. Основные показатели крови животных всех опытных групп находились в пределах физиологической нормы, однако отмечались некоторые различия между группами. Установлено, что у помесных баранчиков зимнего срока ягнения более активный обмен веществ, более высокая энергия роста и, как следствие, большая мясная продуктивность по сравнению с чистопородными животными.

There is a set of farm enterprise elements to be assessed in terms of the effectiveness of their functioning, and there is a set of criteria for assessment of this effectiveness. An algorithm is needed that connects the elements and criteria, and allows determining the optimal variant of this system functioning for building of a mathematical model of the farm enterprise value on the agricultural market. Building of such model is possible with the model of ordered sets restructuring. The relevance of the problem is stipulated by the need to raise Russian farms to the level of peasant farms in the advanced countries. In 24 of the world's most developed countries, farms enjoy significant financial support from the state, reaching up to 40% of their total income [1]. Subsidies in the EU countries reached 45-50% of the value of commodity output produced by farmers, in Japan and Finland-70, in Russia-only 3.5% [2]. This financing gap entailed a number of negative consequences. Over the past 20 years, the rural population has decreased very significantly (by 50-70%) in many areas of the Non-chernozem belt and in some areas of the Chernozem belt in the European part of Russia [3]. Commodity production also decreased. In order to eliminate negative trends, the country's authorities began to practice subsidies. In 2013, the Russian government began providing subsidies in the form of grants in the amount of 1.5 million rubles (and a one-off payment for arrangement-250 thousand rubles), and in 2017 raised the bar to 3,439 thousand rubles [4]. Subsidization is a positive factor, but it is necessary that it be optimal, that is, create the greatest effect in the development of peasant farms.

Вавилова Изучены стимулирующие возможности препарата «Мапрелин ® ХР10 Вейкc». Выявлено, что он на 10 % повышает количество приходящих в охоту свиноматок с синдромом половой депрессии после отъема поросят, сокращает время проявления полового цикла после обработки на 4,6 дня по сравнению с гонадотропным препаратом «PMSG ® » и увеличивает на 8,1 % оплодотворяемость от первого осеменения.
